Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, especially a kind of hot blast air curtain sealing device.
Background technology
In steel manufacture process, sintered ring cold (with cold) UTILIZATION OF VESIDUAL HEAT IN has obtained increasing popularization.But because the design feature of sintered ring cold (with cold) machine self; Encircle between cold (with cold) machine trolley top and the petticoat pipe and can't realize 100% tight seal all the time; Still having the part cool ambient air bleeds; Influence the temperature of utilizing of flue gas, thereby reduced the quality of boiler generation steam, influenced the whole generating system.Especially, influence significantly during winter in the north.In addition, at sintering and ring cold (being with cold) machine blanking pipeline section, because arts demand exists many places to leak out a little, cold wind bleeds and certainly will take away more heats, especially during winter more very.Therefore be necessary to design and a kind ofly can stop bleeding of cold wind, improve the quality that fume afterheat utilizes, reach the hermetically-sealed construction that makes full use of of waste heat.
Summary of the invention
The purpose of the utility model is that design for the deficiency that solves above-mentioned technology a kind of can stop bleeding of cold wind; Improve the quality that fume afterheat utilizes; Reach the hot blast air curtain sealing device that makes full use of of waste heat, and this hot blast air curtain sealing device is cheap, operation expense is low.
The hot blast air curtain sealing device that the utility model designed; It comprises fans entrance baffle door, blower fan, damper, conveying air channel and air curtain distributing pipe; Fans entrance baffle door, blower fan and damper are arranged on to be carried on the air channel, and described conveying air channel arrival end is that hot-wind inlet, the port of export connect the air curtain distributing pipe; Described damper has the performance that hot blast distributes and regulates;
Described conveying air channel; Its hot-wind inlet connects sintering circular-cooler or the non-hot exhanst gas outlet that utilizes section (being sintering circular-cooler or belt-cooling machine III section or IV section or V section) of belt-cooling machine; Perhaps its hot-wind inlet connects sintering circular-cooler or the hot exhanst gas outlet of belt-cooling machine waste heat boiler circulating fan, and perhaps its hot-wind inlet connects the hot exhanst gas outlet of sintering machine main exhauster;
Described air curtain distributing pipe is arranged on the zone of leaking out between central cooler or belt-cooling machine chassis and the petticoat pipe; Perhaps described air curtain distributing pipe is arranged on the intersegmental place of leaking out of sintering machine and central cooler or belt-cooling machine material blanking tube; Perhaps described air curtain distributing pipe is arranged on aforementioned two places simultaneously; Thereby form air curtain at air curtain distributing pipe place, play sealing function, reduce bleeding of cold wind;
The beneficial effect of the hot blast air curtain sealing device of the utility model gained is:
1, takes the non-hot flue gas that utilizes section of sintered ring cold (with cold) machine; Or the hot flue gas (or the hot flue gas that utilizes the sintering machine main exhauster to export) that utilizes sintered ring cold (with cold) machine heat boiler outlet place circulating fan to export; Can effectively reduce cold wind bleeds; Even hot blast bleeds, also can the influence of wind to UTILIZATION OF VESIDUAL HEAT IN of bleeding be dropped to minimum;
2, adopt damper to regulate, can realize reasonable distribution, adjusting the hot blast air curtain.
